Replacement window balance for non tilt single hung Insulate Industries Window

Thanks for your photos. Based on what I see here, you have either the S380-20 that you picked out, or the S385-20, depending on the depth of the bottom shoe. That's the only difference between them. I recommend measuring your shoe and referring to our dimensions to confirm the best match.

Comparison of the S380 and S385 balance shoes.

That's great! Thank you so much, Brandon. We appreciate the business. Please let me know if I can be of any further assistance and I would be happy to advise.
